"Terrible Lizards": How Dinosaurs "Created" Mammals. A conversation with Alexey Semikhatov and Pavel Skuchas.

"Dinosaurs are long extinct" is a widespread myth. The first "terrible lizards" arose before mammals, and some of them continue to survive today. Moreover, dinosaurs had a profound influence on our ancient ancestors. It is to these reptiles that we owe many of our characteristic features, and perhaps even our very existence. Mammals and dinosaurs share a common ancient ancestor, but for hundreds of millions of years they have competed for dominance, a rivalry that continues to this day. In this episode of "Vopros Nauki," Pavel Skuchas, Doctor of Biological Sciences and Professor in the Department of Vertebrate Zoology at St. Petersburg State University, discusses the complex relationship between these two powerful animal groups and their influence on human evolution.
